THE HERO PRIMER
A new tank cartridge primer reduces manufacturing time and critical defects, improving overall ammunition safety for Soldiers.

or today’s Soldiers, maintaining tactical proficiency on the M1 Abrams tank requires tactical and training rounds that are safe and perform as intended. Tactical cartridges for the M1 Abrams must create maximum
impact with minimal use of ammunition. Compared with the wide array of ammunition being used and developed by the U.S. Army, tank cartridges stand out as complicated and require extensive focus on quality and safety assurance. Primers are key components in tank cartridges—ensuring they function reliably is critical, as they are the primary ignition element in the cartridge ignition sequence. Te Joint Program Executive Office for Arma- ments and Ammunition’s Project Manager for Maneuver Systems (PM MAS) manages the life cycle of small-, medium- and large- caliber ammunition, including tank cartridges.
In 2021, the PM MAS tank ammunition team incorporated an improved primer into the Kinetic Energy Tank Training M865A1 and the XM1147 Advanced Multipurpose cartridges. Te primer qualified during the M865A1 cartridge qualifica- tion, saving the government considerable time and money by combining test requirements and engineering efforts. Te new primer improves manufacturability, decreases susceptibility to electromagnetic safety hazards and reduces manufacturing costs. It is known as the Hazards of Electromagnetic Radiation to Ordnance (HERO) primer.
